Never ever trust this business..as she cancels 24 hours in advance
I rarely leave negative reviews, but unfortunately our experience with Rome with Silvia Tofoni was extremely disappointing and completely disrupted our time in Rome. We had booked and fully paid for a Colosseum Underground & Roman Forum tour for Sunday morning. However, on Friday — while we were not even in Rome yet — a man called us asking why we were not at the meeting point for the tour. We immediately explained that our booking and voucher clearly confirmed the tour for Sunday, not Friday. The man informed us that he was “only the tour coordinator” and that our names were on their Friday list. Concerned, I immediately contacted the company to explain the obvious scheduling mistake. Unfortunately, instead of listening carefully or trying to help resolve the issue, the manager abruptly stated that she would refund us. Within minutes, I received the refund notification from my bank account. What was most upsetting was not only the mistake itself, but the complete lack of accountability, explanation, apology, or effort to help us find an alternative solution. As many travelers know, Colosseum Underground tickets are extremely difficult to secure at the last minute, especially over a busy weekend. Because of this error, we completely missed the opportunity to visit one of Rome’s most iconic and important sites during our trip. I attempted to contact the company again afterward by both phone and email in hopes they could still assist us somehow, but my calls were blocked and my emails went unanswered. Mistakes can happen in tourism, but professionalism is shown in how a company handles those mistakes. Sadly, this experience showed very poor customer care and communication. I would not recommend this company based on our experience.
Response from the operator: We sincerely apologize for the frustration and disappointment you experienced. We understand how upsetting it must have been to miss the Colosseum Underground tour, especially given how difficult these tickets can be to secure. We are very sorry that we did not handle the scheduling issue and your subsequent attempts to contact us in the way you deserved. We truly regret that this negatively affected your time in Rome, and we appreciate you bringing this matter to our attention.

Good but cramped, little disappointed it wasn’t more like a tunnel walking tour.
It was good to see the underground. It was smaller than expected and very cramped. Our tour guide was very knowledgeable about all things Roman. She went on for a long time. I’d prefer to have been able to walk more rather than stand around. Thought it would be more tunnels.

Changing title to the tour
The visit was very interesting and especially the guide Alessandra very engaging. I only have one note on the title of the tour. Speaking of the underground Trevi Fountain suggests that you will also visit part of the back of the fountain by accessing for example from the side door in Via della Stamperia. In fact, the Fountain will see what is external and usable to all and you will know stories and legends around the construction of this magnificent work. Very interesting but the title is misleading. In fact, it is about the history and the underground visit, the virgin aqueduct, from the Trevi Fountain to the Barcaccia, passing through Via del Nazarene where you can see the external parts of the aqueduct. The visit to the archaeological area of Vicus Caprarius is the only underground part but it is part of the Trevi district not the fountain. It remains a beautiful and interesting visit to learn to look around.

underground rome you don't expect
We found ourselves with our guide Alessandra in the morning in Piazza dei crociferi next to the fountain of trevi very good at explanation but also very nice to discover an underground Rome that you do not expect then we took a walk until you get to the Spanish Steps explained the route that the aqueduct does under the buildings of the city.

Recommended and interesting visit also for boys
Visit highly recommended. A pleasant afternoon outing made in an afternoon where obviously Trevi was very crowded but carried out very well. We had already made a guided tour in June and returning to Rome for the holidays we did not hesitate to contact her. Emanuele is an excellent guide, very prepared and engaging.

Why this scores 46
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Trevi Fountain Underground Guided Tour Small group: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Rome.
How much does Trevi Fountain Underground Guided Tour Small group cost?
+
Prices start at $65 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Rome usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does Trevi Fountain Underground Guided Tour Small group take?
+
Plan for about 1 hour from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Rome is not rushed.
Is Trevi Fountain Underground Guided Tour Small group worth it?
+
It holds an Outty Ranking of 46 out of 100, which we label "Worth a Look". That score blends traveler sentiment (3.9/5 across 11 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Rome, and how flexible the cancellation terms are.
Can I cancel or reschedule Trevi Fountain Underground Guided Tour Small group?
+
Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.
Is Trevi Fountain Underground Guided Tour Small group suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 1-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Trevi Fountain Underground Guided Tour Small group?
+
Around 4 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Rome can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.
What should I bring or wear?
+
Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Rome and add a light layer if any part of the 1-hour experience runs outdoors or after sunset.
Where does Trevi Fountain Underground Guided Tour Small group start and how do I get there?
+
The exact meeting point and directions are on your voucher once you book, and they sit in central Rome within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.
What are the best things to do in Rome?
+
Rome runs on skip-the-line access. The Colosseum underground, the Vatican before opening, and the catacombs south of the walls all require a licensed operator, and the price gap between the good ones and the rest is smaller than you would expect. We rank by guide credentials, group size and how reliably the promised access actually materialises. On Outty we rank every Rome experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Rome Pasta and Tiramisu Class: Ravioli, Fettuccine & Fine Wine 5*, Pasta Making & Wine Tasting with Dinner in Frascati from Rome, Rome: Pizza & Tiramisu or Gelato Class with Flowing Fine Wine 5*. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.
When is the best time to visit Rome?
+
April, May, September and October. August is hot and half the city is shut. Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.
How many days do you need in Rome?
+
Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.
Do I book through Outty or through the operator?
+
Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
